| 摘 要： | 本文分析了有限个、有限长的矩形序列卷积而得到的序列的频率特性;找出了最佳频率特性的单元序列长度的比值。结果表明,具有最佳频率特性的序列可做为有限冲激响应滤波器设计中的窗函数使用,其性能优于布莱克曼窗。

| Abstract: | This paper analyses the sequent frequency characteristic of the finite sequence convolution based on finite retangle sequences, and derives the ratio of unit sequence length of optimal frequency characteristic. The result shows that the sequences with optimal frequency characteristic can be used as the windows in desining finite impulse response filler, and its characteristic is superior to Blaokman window's |
